jsPDF更改页面格式 [英] jsPDF change page format

问题描述

我具有在页面上设置页脚的功能.但是我想使代码更加灵活，并在文档为'a4'或a3'时在其中希望将页脚设置在不同位置的地方添加if语句.

I have a function to set a footer on a page. But I want to make the code more flexible and add an if statement where I want it to set the footer on a different position when the document is an 'a4' or a3'.

function footer(){
    doc.setFontSize(11);
    doc.text(180,280, 'Seite ' + doc.page);
    doc.page ++;
    }

但是启动页面后，我找不到用于更改格式的参数:

But I can't find the paramater to change the format after the page has been initiated:

var doc = new jsPDF('p', 'mm', 'a4');

我尝试过:

doc.format('a3');
doc.setFormat = 'a3';
doc.setPageFormat('a3');

但没有效果.

即使在"new jsPDF"启动之后，有人知道在代码中的任何位置更改页面格式的参数吗?还是这根本行不通?

Does someone know the paramater to change page format anywhere in the code even after "new jsPDF" initiation? Or does this simply not work?

提前谢谢！

推荐答案

您可以在每个新页面上设置格式和方向:

You can set format and orientation on each new page:

doc.addPage('a3', 'portrait');

方向是人像"或风景"

Orientation is either 'portrait' or 'landscape'

或者，您也可以设置高度和宽度:

Alternately you can also set the height and widht:

doc.addPage(newWidth, newHeight);

在这种情况下，单位将与您的jsPDF实例化('mm')中的单位相同:

In this case the units will be the same as in your jsPDF instantiation ('mm'):

var doc = new jsPDF('p', 'mm', 'a4');
